A French psychologist writes8 that when a child has a caprice—for instance, his mother is in a shop with him and he suddenly demands a toy—the mother should remain extremely calm and gently explain that buying the toy isn’t in the day’s plan. Then she should try to bypass the caprice by redirecting the child’s attention, for example by telling a story about her own life. “Stories about parents are always interesting to children,” the psychologist says. (After reading this, in every crisis I shout to Simon: “Tell a story about your life!”)
